在过去的10年中，冷喷涂工艺已经成熟，导致在许多工业部门中发布的关于系统创新和工艺实施的专利显着增加。自Irissou等人于2008年发表的首次知识产权专利审查以来，涵盖了冷喷涂的早期发展，从1915年的不成功尝试到俄罗斯和美国的现代发展，共授予了300多项新专利。本章的动机是提供一个概述，在不断扩大的领域的冷喷涂技术的最新，关键的发展。使用Questel（巴黎，法国）的ORBIT软件进行专利检索，冷喷涂工艺的定义包括：冷气动态喷涂（CGDS）、动力喷涂（KS）、超声速颗粒沉积（SPD）、动态金属化（DYMET）或动力金属化（KM）。本文仅评述了与冷喷涂工艺无关的美国专利，主要包括三个方面：（1）设备和方法;（2）原料;（3）应用。设备和方法部分包括旨在改进冷喷涂系统和系统控制的专利审查。原料部分包括原料材料设计，以提高喷涂性和目标化学、机械和微观结构材料性能。冷喷涂应用部分涵盖了保护涂层、焊接、钎焊和部件修复以及增材和近净形制造领域，这些领域对汽车和航空航天工业非常感兴趣。审查的其他专利包括生物医学和电子设备领域的冷喷涂工艺应用。
In the past 10 years, the cold spray process has gained in maturity leading to a significant increase in the patents released on system innovation and process implementation in number of industrial sectors. Since the initial intellectual property patent review published by Irissou et al. in 2008 and covering the early development of cold spray from unsuccessful attempts in 1915 to the modern development in Russia and USA, over 300 new patents were awarded. The motivation for this chapter was to provide an overview of the recent, key developments in the expanding field of the cold spray technology. The patent search was performed using the software ORBIT from Questel (Paris, France), and the definitions of the cold spray process included: cold gas dynamic spray (CGDS), kinetic spray (KS), supersonic particle deposition (SPD), dynamic metallization (DYMET) or kinetic metallization (KM). Only the US patents, which were found to be excusive to the cold spray process, were reviewed.Three main topics covered by the patent review consist of: (1) apparatus and methods, (2) feedstock and (3) applications. The apparatus and method section includes a review of patents aimed towards the improvement of the cold spray systems and system control. The feedstock section includes feedstock material design for improved sprayability and targeted chemical, mechanical and microstructural material properties. The cold spray applications section covers the field of protective coatings, welding, brazing and component repair as well as additive and near-net-shape manufacturing, found to be of great interest to the automotive and aerospace industries. Other patents reviewed consist of cold spray process applications in the field of biomedical and electronic devices.
